Explanation: In the prelude to Caesar's Civil War in the Late Roman Republic, Caesar was engaged in negotiations with the Senate due to his enemies in Rome wanting to have him executed for the crime of being too popular. Though the negotiations started fruitfully, the intransigence of the conservative wing in the Senate eventually forced the moderates to offer a hardline position, wherein Caesar was offered no guarantees against being executed in exchange for giving up his legions and returning to Rome.
For obvious reasons, Caesar was not keen on this 'generous' offer, and instead opted to return Rome's legions to the Republic in a more... direct way.
